Application med my 2, 191s. serial No. 294,325.

To all whom t may concern Be it known that I, WILLIAM W. SABIN, a citizen of the United States, and a resident of the city of Portland, county of Multnomah, State of Ore on, have invented a certain new and use Improvement in Demountable Lamp-Brackets for Automobiles, of which the following is a specification.

The object of my invention is to provide a lamp-bracket of inexpensive construction adapted for being demountably secured on the upright post of the windshield of anantomobile. Also to provide means .for locking the bracket, and the lamp globe or light carried thereby, i-n place, so that 1t can not be removed by any other person than the one l possessing the key to the lock.

A further object is to so arrange the lamp bracket that the vlight carrying part may be readily demounted and carried about as la trouble lamp.

I attain my objects in the device illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of my device; Fig. 2 is a longitudinal, vertical section with respect to- Figs. 1 and 3, being taken on the line 2-2 of Fig. 3, with the lamp holding arm arranged, however,- in lon tudinal alinement with the body of t e bracket, and the mirror carried by the lamp member disposed at right angles to the latter; these arbitrary arrangementsof said arm and bracket being adopted merely as a matter of convenience in illustrating in assemblage all the parts embodied in my lamp bracket;

Fig. 3 is a longitudinal section on the line 3-3 of Fig. 1';

Fig. 4 is a vertical cross section on the line 4--4 of Fig. 1, looking in the direction pointedby the arrow;

Fig. 5 is a sectional detail of the spool on which the cord is woun'd; and

Fig. 6 is a detail of the means for clampin the lamp post against' rotation.

he body crease of myvbracket is of lrectangular form, except at the bottom, and comprises two half parts a, b, hinged together at c, and provided with companion alf neck portions d, adapted or beingv clamped on the post of the windshield frame. Nuts and bolts e secure the two bracket parts together. The two bracket parts' are further locked together by a lock mechanism which is understood to be contained in the tated by means of a key inserted through the lock shield g, so as to cause the arm f2 to assume one of the two positions shown in v full lines and dotted lines in Fig. 2.

The arm f2 of the spindle f engages with a longitudinally slidable bolt h, provided with a slot c', lin which said arm bears. The bolt h has a concaved end j adapted for engaging with the peripheral groove lc of the lamp-supporting post c having a curved upper end. The lock mechanism is so constructed that in the partial rotation of the spindle f to the right it will first move the bolt la sufficiently to disengage the lamp post c; and in the further rotation ,of the spindle f to the right, the arm f2 of the latter will be withdrawn from the bolt l1, completely, 'so that upon the removal of the bolts e the two wall sections, a, b, of the case may be'opened on their hinge. Thus it is evident that neither the lamp post can be removed nor the: bracket detached from the post of the windshield frame by any person not possessing the key for the lock. Thelamp post lc `is rotatably mounted in the part, a, of the case, and on its upper end is swiveled, as at Z, a lamp carrying arm l', supporting at one end a reflector m, in which is inserted an electric light globe n. l

In the opposite end of the arm Z is threaded a piece o, having a ,hinge o', to which is hinged at p an arm p, carrying a mirror g; the hinges o' and p cooperating to forma universal joint. Y

In order to rigidly hold the lamp arm l in the position to which it is adjusted, I

provide a concaved clamping head 1'., mount-V ed on a pin 1" projecting from the piece o, and bearing on a spring s, so that by screwg up the piece o tightly the parts will be jammed together. h

In the lowerfpart of the frame is rotatably mounted aspool t. Onthc spool t is wound an electricl light cord. One hub of the spool is assumed to be connected, as at u, with the poles of an electric battery, not shown, and the electric cord end lv is also connected to these poles. The free end'of the cable 'v is electrically connected with the lampV socket lw in the usual manner; and the lamp socket 'is of the usual construction. The spool is 2o in Fig. 2.

ment bein such that when the cord lv is pulled olf t e spool t, as in the case of ,removing the lamp post lc and using the lamp for illuminating some part of the automobile, then the coll spring :r is placed in tension, and as the pull on the cord is released the coil spring will act to Wind it up again on the spool.

The lamp post is'secured against rotation bya 'am screw y threaded into the case side b and detailed in Fig. 6. The jam screw g is provided with a reduced end y on whic is rotatably mounted a concaved clamping head a; and a spring 2 is mounted on the reduced end y so as to obtain a. constant bearing of the head .e on the perlphery of the lamp post. The jam screw gis made with a handle V3. Fig. 6 serves also to illustrate the details of construction of the clamping head fr and related sprlng s, shown The wire cord lv leads from the spool t through a hole 4 in the top of the bracket part', a, and through a hole 5 in the lamp carrying arm Z', said lamp carrying arm being hollow.

1. A lamp bracket comprismg two parts hin ed together, each part provided with hal of a clamping neck for aiiixing to` a support, a lamp post removably and rotatably mounted in one bracket part, means for locking the bracket parts together, means operated by said locking-means preventing the removal of the lamp post wh1le the bracket parts are locked together, and means for holding the lamp post against rotation.

2. A lamp bracket comprising two parts hinged together, each part provided with half of a clamping neck for ailixing to a support, a lamp post removably and rotatably mounted in one bracket part, means for locking the bracket parts together, means operated by said locking means preventing the removal of the lamp post while the bracket parts are locked together, means for holding the lamp post against rotation,

post,- and means `for holding said arm against rotation. Y A .v

3. A lamp bracket comprising two parts hinged together, each part provided with hal of a clamping neck for ailixin to a support, a lamp post removably an rotatably mounted in one bracket part, means for locking the bracket parts together,

means operated by said locking means `reventing the removal ofthe lamp vpost lw ile the bracket parts arelocked together, means for holding the lamp post against rotation, a lamp carrying arm swiveledon the lamp post, means for holdin said arm against rotation, and a mirror jointedly supported by the lamp carrying arm. v

4. A lamp bracket comprising two parts hinged together, each part provided with hal of a clamping neck for alixn .to a support, a lamp post removably an rotatably mounted in one bracket part, means for locking the bracket parts together, and saidlocking means including a. member engaging with and rotatably securing the-lamp against removal while the bracket parts are locked together;

5. A lamp bracket comprising two parts hinged together, each part provided with half of a clamping neck for afiixing to a support, a lamp post provided with a peripheral groove and removably mounted in one bracket part, means for locking the bracket parts together, and a bar reciprocable by the locking means and engaging with the peripheral groove in the lamp post.

' 6. A. lamp bracket comprising two parts hinged together, each part provided with half of a clamping neck for aiiixing to a support, a lamp post removably mounted in one bracket part, means for locking the bracket parts together, means operated by said locking means preventing the removal of the lamp post while the bracket parts are locked together, a spool journaled in the bracket, and an electric cord wound on the spool, connected with the lamp socket carried by the lamp post.
